Build a ported box, sealed box for your low-frequency speaker. That 18 no longer contains air to feed your woofer (s). Its very easy We can provide you with comprehensive Subwoofer Box Calculator for online creating a high performance subwoofer enclosure. The sub and port take up about 18 of that volume. This free volume calculator computes the volumes of common shapes, including sphere, cone, cube, cylinder, capsule, cap, conical frustum, ellipsoid. The calculator also returns the dimensions of the squared box in inches. The total available volume you just calculated is the box’s gross volume. However, this can be automatically converted to compatible units via the pull-down menu. Subwoofer Enclosure Volume (V): The calculator returns the volume in cubic inches. Third, consider the type of subwoofer you want. This will help you determine how much power you’ll need from your amplifier. Second, calculate the volume of the space. You’ll need to know the dimensions in order to choose the right size box. ft.) Calculating Internal Volume For Complex-Shaped Enclosures. Simplify again, Volume 1.6786 Cubic Feet Gross Volume (can be rounded to 1.68 cu. Accurate calculation of enclosure volume for your subwoofer box is essential in designing a properly functioning subwoofer. INSTRUCTIONS: Choose units and enter the following: First, measure the space where you’ll be installing the subwoofer box. Calculating the volume of Mel's Mix you'll need for a Square Foot Garden box isn't as complicated as it first seems. Now calculate the internal volume of the enclosure in Figure D by using the volume equation. To display diagrams you must fill in all appropiate fields (zeros disables the curves).The Subwoofer Enclosure Volume calculator computes the volume based on the air compliance of the subwoofer, the subwoofer tuning frequency and the speaker resonance frequency. You are also able to calculate a Closed-Box if you make the value of the vent diameter very small (i.e 0.01).Īttention: You can put in your own Thiele/Small-parameter only if the speaker-select "parameterinput" is selected. The graphic display is intended as a way to visualize some of the proportions as you manipulate the size of the box. Red: any construction of your enclosure using the same Thiele/Small-parameter.Height Width Total (Ft3) Due to rounding, the total number shown above will. Blue: Closed-Box (without filling material) aligned with Thiele/Small-parameter and a desired Qtc. Subwoofer Box Dimension Calculator Box volume (Ft3), Depth inches.Black: Vented-Box with Thiele/Small-Parameter (Bullock alignment).The colors of the curves in the diagrams for frequency response, step response, group delay and voice-coil impedance have the following meaning: On this page you are able to calculate a speaker enclosure with Thiele/Small parameter.
